JEWELRY-FASTENING DEVICE.

SPECIFICATION forming part of Letters Batent No. 772,711, dated October-18, 1904.

Application filed May 11, 1904.

To all whom it may concern.-

Be it known that 1, ROBERT FIsoHER, acitizen of the United States, and a resident of the city of New York, borough of Brooklyn, in

the county of Kings and State of New York, have invented a new-and Improved Jewelry- Fastening Device, of which the following is a full, clear, and exact description.

This invention relates to jewelry-fastenings, and more particularly to a device adapted for attachment to scarf-pins and the like to secure the pins in the scarfs or other garments into which they are inserted.

The principal object of the invention is to provide a device of the character specified which is small, simple, and inexpensive, which may be quickly applied to a scarf-pin and when so applied will automatically grip the pin, so as to hold it securely and preventits] accidental removal from the garment in which 1t 1s lnserted'.

Afurther object of the invention is toprovide a device of the character specified whichv obtains a firmgrip upon the scarf-pimwhich is not easily deranged, and which will operate successfully upon pins of different diameters.

thereof.

Reference is to. be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the views Figure 1 is a view of a scarf-pin having the fasteningdevice applied. thereto. Fig. 2 is a front elevational view of the device with the cover removed, the device being shown out of use. Fig. 3 is a view similar to Fig. 2, but showing the device in use. Fig. 4 is a sectional view upon the section-line 4 4 of Fig. 2.

Serial No. 207,398. (No model.)

Fig. 5 is a detail perspective view of the body of the device, and Fig. 6 is a detail perspective view of the gripping-block.

Referring to the drawings, P designates a scarf-pin comprising a pin 10 and an ornamental head H. The pin 10 may be of any ordinary dimensions and is sharpened at its lower end, as usual. The fastening device proper comprises a body portion 1, which consists, preferably, of a disk of metal provided with a wedge-shaped chamber 2, one side of which coincides with the diameter of the disk throughout the greater portionof its length, and the other side is disposed at an oblique angle to the said diameter. The chamber 2 extends to the periphery of the disk at its widest end, and at the narrower end the chamber terminates somewhat short of the periphery. The disk 1 is diametrically bored, as shown at 3, and the bore 3 is disposed along the diameter of the disk which corresponds to the longer side of the chamber 2, the bore and the chamber communicating throughout the entire length of the chamber, as best shown in Fig. 2. Within the chamber 2 in the disk a gripping-block 4 is arranged for sliding movement. The block 4 presents a serrated gripping-face 5, and upon the back of the block a lug 6'is formed, which has'a rounded end which engages with the shorter side of the chamber 2, along which it slides smoothly. Upon the lug 6 a projection 7 is formed which extends through a camslot 8, formed in the cover 9 of the device. The cover 9 consists, preferably, of a shell 10' and a plate 11, which is secured in position by crimping the edges of the shell thereover, as best shown in Fig. 4.

In'order to bring the gripping-block 4 automatically into engagement with a pin when thrust through the bore 3 of the disk 1, a spring 12 is provided in the chamber 2-of the disk and disposed parallel to the shorter side of the chamber, in which position the spring is held by setting one end ofthe spring against a shoe 13 having upturned ends, as shown in Figs. 2 and 3. The shoe 13 is secured in position by the engagement of one of the upturned ends with a notch 14, formed in the periphery of the disk 1 adjacent to the wide end of the chamber 2, and the other upturned end of the shoe forms a shoulder against which the spring 12 catches and is so prevented from sliding off the shoe and assuming an inoperative position within the chamber 2. The spring 12 being disposed between the lug 6 and the shoe 13 tends to force the block at upward in the chamber 2, and the engagement of the lug 6 with the inclined side of the chamber 2 forces the block laterally toward the bore 3, into which the pin 1), of the scarf-pin may be introduced.

The action of the fastening device above described may be very readily understood from a mere inspection of the drawings. IVhen the pin 1) of a scarf-pin is introduced into the upper end of the bore 3 in the fastening device, the pointed end of the pin passes downward easily through the bore and engaging the upper end of the gripping-block forces the block downward and at the same time pushes it laterally, so that it opposes no obstruction to the downward passage of the pin through the fastening device. As soon, however, as the pin has been thrust through the fastening device to the desired extent and pressure upon the head H of the pin is removed the action of the spring 12 upon the gripping-block forces it upward in the chamber 2 within the disk 1. The serrations upon the gripping-face 5 of the block are then brought into engagement with the pin, and as the said serrations are directed downward another upward pull upon the pin tends to draw the gripping-block upward, and at the same time to force it into more positive engagement with the pin.

From the foregoing description of the invention and the drawings illustrative thereof it will be readily seen that when a scarf-pin is forced into a scarf and the fastening device forming the present invention is applied thereto the spring in the chamber within the device will act automatically to bring the grippingblock into engagement with the pin, and the accidental removal of the pin will be positively prevented as long as the fastening device is applied thereto. Another upward pull upon the pin will merely bring the fastening device. into engagement with the back of the scarf or other garment into which the pin is thrust, and the downward pull exerted on the fastening device thereby will cause the gripping-jaw to jam tightly against the pin and positively prevent its withdrawal.

In the construction of the device any suitable material may be employed; but it is desirable that the parts be made wholly of metal, and in the construction of the gripping-block hard steel is preferable, because when formed of steel the serrations upon the gripping-face retain their sharpness and obtain a better hold upon the scarf-pin. The exterior of the fastening device may be ornamented in any suitable manner, and, if desired, the cover or casing of the device may be made of gold or other precious metal, though this is not essential.

In order to release the device when it is desired to remove the scarf-pin, the projection 7 upon the lug 6 must be depressed in the cam-slot 8 in the cover of the device. The downward movement of the projection T in the slot 8 causes the gripping-block -l to move laterally away from the pin, which may then be removed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent' l. The combination in a device of the character specified, of a body having a bore and a .chamber of wedge shape communicating with said bore, one side of the chamber being coincident with the axis of the bore and the other side disposed at an oblique angle thereto, a gripping-block having a serrated gripping-face disposed parallel with said bore and having a portion in contact with the other side of said chamber, and a spring located parallel to said oblique side of the chamber and operating upon said block to force it antomatically into engagement with a pin when thrust through said bore.

2. The combination in a device of the character specified, of a body having a pin-passage therein and a wedgeshaped chamber communicating with said passage along one side, a sliding grippingblock within said chamber, said block lying normally in contact with the side of the chamber opposite the pin-passage, a spring engaging said block to throw it automatically into gripping engagement with a pin in the pin-passage, and a shoe attached to said body and holding said spring parallel with the side of the chamber opposite the pin-passage.

8. In a device of the character specified, the combination of a casing, adisk located in the casing and having a diametrical passage through it and a trapezoidal chamber communicating with the passage, a gripping-block in the chamber adapted to project into the passage, and means forforcing the block toward the passage.

4. In a device of the character specified, the combination of a casing, adisk located therein having a diametrical passage through it and a trapezoidal chamber communicating with the passage, one side of the chamber being coincident with the axis of the passage and the opposite side disposed at an oblique angle thereto, a gripping-block having a serrated gripping-face disposed in the chamber parallel to the said bore and having a portion in contact with the oblique side of said chamber, and a spring located parallel with the oblique side of the chamber and adapted to operate upon said block to force it automatically into engagement with a pin when forced through said passage.
